    Abstract:
    The discrepancy in the literature about the immediate results after carotid endarterectomy in the presence of occluded or seriously stenotic contralateral carotid artery, has encouraged a retrospective study on 230 patients subjected to 255 carotid endarterectomies. 63 operations (group 1) were carried out in the presence of occluded contralateral carotid artery (40 operations) or of seriously stenotic contralateral carotid artery (23 operations). In the remaining 192 operations (group 2) the contralateral carotid artery was normal or not significantly stenotic (less than 60% of diameter reduction). The indication for surgery and age and sex distribution were similar in the two groups. No operations were performed during acute stroke. Patients with previous stroke underwent surgery only after at least 1 month from the onset of symptoms, in stable neurological conditions. All the patients were operated on under general anesthesia and with systemic heparinization; the indication for intraluminal shunt was made on the basis of clinical evaluation, of back pressure value and, in 106 operated cases of somatosensory cortical evoked potentials. At the end of every operation, ultrasonographic and/or angiographic instrumental controls were carried out. No statistically significant difference was evidenced in the incidence in groups 1 and 2 of postoperative transitory neurological insufficiency (both 3.2%, P greater than 0.8), of permanent neurological insufficiency (0% and 1%, P greater than 0.9), of mortality because of neurological (3.2% and 1%, P greater than 0.5) and non neurological causes (1.6% and 0%, P greater than 0.1).(ABSTRACT TRUNCATED AT 250 WORDS)
